Thanks guys! Lee and Bryan were very kind and helpful. Loving my car so far.
2020 GMC Sierra 3500 SLT review
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

The whole team was super helpful.
The whole team was super helpful. Brent, Gene and Ken did a great job. Brent took a lot time to make sure we had all the information we could take in on our new truck and said to call anytime we needed help.
2020 GMC Sierra 3500 SLT review
Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Carsandpickups.com of Dallas review
Nothing but great things to say about this dealership.
Nothing but great things to say about this dealership. They got me into a 2021 Dodge Durango R/T and even beat the interest rate I had from my own bank — all during the winter storm that hit DFW. Communication throughout the entire process was excellent. The online price was exactly what I paid (plus tax). No hidden fees or surprise add-ons like you see at some larger dealerships, which was very important to me. Alfonso went above and beyond by checking on the vehicle after the storm to make sure there was no damage and even advised me to wait to test drive until the roads were safe. After purchase, I had a small sensor issue (likely from the freezing temps), and they quickly connected me with a trusted mechanic who fixed it right away. Best car-buying experience I’ve had. I’ll definitely be referring friends and family.
